All about nitrogen.
The growth of all organisms depends on the availability of nutrients - and none is more important than nitrogen, an essential building block in plants.
Nitrogen is difficult to absorb by plants because of the binding structure of its atoms. It is estimated that 40% of all chemical nitrogen fertilizer additions are never used by plants.
Microorganisms have a central role in almost all aspects of nitrogen availability. Some bacteria convert nitrogen into ammonia by the process called nitrogen fixation; other bacteria bring about transformations of ammonia to nitrate, and of nitrate to nitrogen and other nitrogen gases; many bacteria and fungi degrade organic matter, releasing nitrogen for reuse by other organisms.
Bottom line... the microbes in Great Big Plants Energy Drink for Plants facilitate the nitrogen cycle by transforming nitrogen into a form your plants can efficiently use.
